so like, it has been customary Patented Jan. 2 1937 UNITED srjiras PATENT OFFICE I. of W Fillaucks, Inc., Seattle, Wash, a corporation ashington Application July 2, 19:5, Serial No. 29.450 Claims. (cl. 144-409) This invention relates to the art of forming assemblies inbundles, and more particularly to methods of forming box-sides and similar articles.

a An object of the invention is the provision of a procedure whereby glued assemblies; such for instance as box-sides, i. e. articles whereby the top, bottom, side or other walls of a box may be formed, or similar constructions may be held under pressure for the setting of the glue and made ready for shipment in groups.

More'speciflcally, it is an object of the invention to avoid the time-consuming and expensive operations which have been utilized up to the present time for the formation of assemblies of the character under consideration and in making them ready for shipment.

Other objects of the invention will in part be obvious and will in part appear hereinafter.

go e invention accordingly comprises the severa1 steps and the relation and order of one or more of such steps withrespect to each or the others thereof, which will be exemplified in the method hereinafter disclosed, and the scope of the ap-' g plication of which will be indicated in the claims. For a fuller understanding of the nature and objects of the invention, reference should be had to the following detailed description taken in con-- nection with the accompanying drawing, in

so which:

.In the manufacture of glued box-sides and the to assemble two or more slats side by side with a cross cleat at each end glued to the slats and holding them in proper relative position. These have ordinarily been gathered in groups and bound betweenscrew 45 clamps or in complicated and expensive machines until the glue wasset; and usually for convenience tied loosely across the middle with a string so that the various assemblies could be-handled as a bundle. This time-consuming, cumbersome 50 and otherwise objectionable practice, recognized as undesirable, but nevertheless deemed unavoidable, necessitated multiplication of equipment and compelled long waits before the product was ready for shipment or storage and until the 5; equipment could be used again, since in all casesthe work was kept in apparatus the full time required for the glue to set. The present invention departs sharply from such unsatisfactory procedure and makes for greatly increased simplicity and emciency. It contemplates a method 5 of making box-side assembly bundles ready, at the instant of completion of the bundle, for immediate shipment or storage without waiting for the glue to'set. In theperformance of the single step of forming an immediately available 10 bundle of box-side assemblies, the ,method, at thesame time and without further equipment than that used in the bundling, provides and maintains the condition requisite to the proper setting or the glue and proper completion of the 5 box-sides.

Individual box-side assemblies are produced in e o na y way by pp yin glue at the ends of the slats I or to the face of the corresponding cleats 2, as may be the more convenient. After zu being glued, these assemblies to the number oi say twenty-four or twenty-five, are then stacked by hand, or by machine, with the cross cleats at each end aligned in sets, as best shown in Fig. 1. The two exterior, assemblies, on the top and on the bottom in the said figure, have their cleats on the outside, thus protecting the more delicate slats. Before the glue has set, the assemblies are then, according to the invention, bound closely into a bundle, with the cleats in close contact with their respective slats, by tightly applying ties 3 (3' in Fig. 4) over the cleats. as indicated in all of the figures, and securing them firmly against slipping or release, as indicated at l (5' in Fig. 4).

The collecting, arranging, tie-applying and securing procedures need not be sharply isolated or distinct steps but may go on to some extent at the same time or merge into each other. Much the best and most eii'ective ties are flat steel straps of known construction not necessary to 40 illustrate in detail. Wire or rope may be used, but to less advantage than the flat steel straps. Where wire is chosen protective pieces should be interposed be ween the end edges of the cleats and the wire avoid cutting into the cleats un- 5 duly. Rope has the defect for this use of being subject to stretching. In Fig. 1,' the box-side assemblies after being glued and stacked have been bound closely into a bundle with the cleats in close contact with their respective slats by 5 tightly applying to each and set of cleats the steel strap I running lengthwise of the cleats approximately axially thereof and enclosing the set, and firmly securing each strap, one end of which is run through, or lapped with, the other and as outer cleats.

clinched, or otherwise fixed at 4 against return movement, thus tying the parts tightly and permanently together in the correct relative position and under the pressure required to insure the proper setting of the glue. This provides a neat package with a moderate amount of strapping and with adequate distribution of pressure on the glue line. Greater rigidity and greater uniformity of pressure is obtained by the location of the cleats of the two exterior assemblies on the outside, as indicated above.

The method which resulted in the bundle of Fig. 2 is the same as that already described'in the gluing and stacking of the assemblies, but the ties, steel straps 3 being shown, are passed crosswise of the cleats and lengthwise of the slats around the entire bundle. These are drawn tightly and have their ends fastened securely as in Fig. 1. Two straps symmetrically arranged are effective and sufficient, but one will serve where the bundle is narrow. As will be evident the crosswise straps exert a crosswise component tending-to slide each outside cleat inward on the slats out of its proper position if the two exterior assemblies are freshly glued. It is best, therefore, to insure the fixity of these cleats, as may be done by selecting these particular assemblies from previously glued box-sides wherein the glue hasset. This manner of application gives good distribution of pressure by greater. length of strapping. q

Themethod which produced the bundle of Fig. 3' differs from either of these already described in utilizing aligned spaces between slats which form slots adjacent to each end set of cleats which can thus be completely encircled and so bound together by short straps or ties 3 tightly drawn and firmly secured at 4. In this way the cleats are'placed and held in close contact with their slats and the glue sets during shipment or storage as in all the other forms of the method. Two symmetrical straps are best and suificient.

The bundle shown in Fig. 4 is bound and held by short steel'straps 3' having inturned ends 4' held fast by tangs" 5' punched into the respective The straps having been tightly drawn, the tangs serve to maintain the bundle in tightly drawn relationship, so as to assure that the glue'will set under'properconditions and that the bundle may be handled as for shipment or storage as soon as the straps are in place. The straps extending over the ends of the cleats, as exemplifiedat the right of Fig. 4, serve to prevent lateral slipping of the cleats and the straps extending over the edges of the cleats, as exemplified at the left of Fig. 4, serve to bind the bundle firmly at more orless spaced portions along its edge. As many straps as desired may be used at each end of the bundle, or at such other points as cleats or other smaller surface members are provided. The method is essentiallyas described in connection with the other As will be apparent, the invention in its broader that the method as eX- aspects, is adapted for use in a variety of cases where assemblies of small-surface members with large-surface members are to be formed by gluing and grouped in bundles.

Since certain changes may be made in carrying out the above method without departing from the scope of the invention, it is intended that all matter contained in the above description shall be interpreted as illustrative and not in a limiting sense. i
